They are cheap to replace and a little contorting & 22mm crowfoot was needed for me to get mine done. Let me know if I can help more.
Thanks again to the forum regulars who provided me with the O2 sensor help!

Well, I got under the ML and replaced the o2 sensor (bank1, sensor 1) and the light and code still read "o2 sensor malfunction." I'll drive it another couple days prior to visiting the dealer. It may just need a couple of days to recalibrate.
It took a total of 25 minutes (including lifting the ML) to replace the o2 sensor. A bit tight, but you are right, completely doable.
Thanks again.
